No rpc.lockd of NFS client ?

Hi, I am new to opensuse 10.0. When I use NFS client (/etc/init.d/nfs start) to start the NFS mount, it does mount what I wrote in /etc/fstab. But the problem is that I did not see any rpc.lockd running in this client. This will cause problem when some program tried to lock some file. Does anyone know how to do that in OpenSuSE 10.0 ? Thanks. -- Steven Shiau
